TSB Footwell Water Ingress - cabin filter IATSB002996

This will not fix the issue. I'm of the view it's straight up condensate forming on the AC duct where insulation is not present and dripping straight down the centre console plastics on to my feet. There are a few threads on this and findings I thought suggested this was the issue and the fix requires a removal of dash plastics to give access to AC ducting...

This is what my dealer did

Hi.
I have been having ongoing issues with water coming into the passenger footwell from the aircon. My car has been back to the dealers many times for this - but yesterday I was informed about a factory recall.
See attached FYI.
I hope this helps.
Cheers

My local agent / dealer did that to mine nearly a year ago and it’s been mostly fine ever since. In the worst of the humidity we had one trip where my wife complained of a tiny bit of water. That’s it for 12+ months.

My vehicle spent a week at the service centre last week on the continuing HVAC issues. Looks like more wrapping on the pipes were done, similar to the post above by Larry.

20 minutes after picking the vehicle up and driving away water was again seen forming in the footwell. Not the occasional drip, but enough water to make anything in the footwell quite waterlogged.

IA being consulted, again.

I think there is the condensation issue, and another one, which myself and others are encountering.

Insulating the pipe is just a temporary fix. It doesn’t fix the initial core problem. It’s a bit like Ineos punching holes in the lower rubber door seals rather than fitting the seals properly in the first place.

I’ve managed to fix mine by simply, first thing in the morning, prop up engine bay to service position (highest point). Top up both coolant reservoirs to the max level indicator ensuring both sides are equal. Surprising how much coolant needs topping. Coolant level has gone down as air has been displaced. This should work. If it doesn’t, carry out a bleed procedure, wait until engine is stone cold (following day) and then top up coolant to max level. It has worked for me, in the summer of 2023, 2024 I used to get drips down the side the central dash onto the passenger mat, condensation on the windscreen during heavy rain and condensation (icing up) on the outside in winter (centre lower windscreen).

Luckily I have rubber mats. Been back to dealers twice and Ineos said no fix. Had the HVAC unit changed and still the same. Early 2025, seen a post on here about checking coolant as some engine had over heated and I discovered that my coolant tank was only 3/4 full on one side and nearly full on the other.

During the last month, the weather has been great for us in the UK, I can report no more drips.
